Mr. J. F. Stephens exhibited two species of Coccus, one found 

 in great profusion on Rihes sanguineum, the other on the apple 

 tree ; and, for comparison with these, he also exhibited specimens 

 of the species infesting the orange tree. 



Mr. S. Stevens exhibited a remarkable variety of Polyommatus 

 Adonis, taken at Torquay, in which the upper surface of the wing 

 was of a fulvous colour; also a specimen of Deilephila Livornica 

 (Esp.) from the same locality. He likewise exhibited numerous 

 beautifully-preserved specimens of Lepidoptera, taken by himself 

 in Devonshire, amongst which were Hypena Crassalis, Eupithecia 

 mgrn-punctata, Margaritia longalis, Anticlea s'lnuata, Emmelesia 

 bifasciata, Xanthosetia inopiana, and other species, rare in Great 

 Britain. He stated that the larva of the last-named species feeds 

 on a species of Pulicaria. 



Mr. Westwood informed the Society, that he had recently made 

 some very interesting observations on Sitaris humeral'ts, which he 

 hoped shortly to be able to publish. He brought to the Meeting 

 many specimens captured by himself in Oxfordshire, for distri- 

 bution amongst the members. 



Mr. E. Doubleday read a description of a new species of Go- 

 nepteryx, of the section for which Dr. Boisduval had proposed the 

 name of Dercas.
